Clip

A clip for coupling a first member where an erect portion in which a first through-hole is formed is protruded, and a second member where a second through-hole into which the erect portion is inserted to pass through is formed, and coupling a coupling hole defined by the first through-hole passing through the second through-hole and the second member, comprising:

• a flexible cylindrical portion having a predetermined center axis line, opening two ends, and formed so that a distance from the center axis line to an outside surface is different in a rotational direction around the center axis line,
• wherein the cylindrical portion has the center axis line orthogonal to an axis line of the coupling hole, and is inserted into the coupling hole rotatably between a first rotational position and a second rotational position around the center axis line, and
• the cylindrical portion is set to have a distance between the center axis line and the outside surface in such a way as to be loosely fitted in the coupling hole at the first rotational position and to be clamped between hole walls of the coupling hole at the second rotational position.
